论文摘要
在本文中，我们通过考虑不同的参数$δ$和$ r $的价值，在同型和空间均匀的Friedmann-Robertson-Walker（FRW）宇宙中研究了Sharma-Mittal全息暗能模型（SMHDE）。我们通过分析态构建层次结构和扰动的增长率来检查SMHDE模型。状态基层次结构的进化轨迹$ s_3^1 $，$ s_3^2 $ $ $ s_4^1 $，$ s_4^2 $对redShift z，在整个宇宙评估中表现出令人满意的行为。研究暗能量模型的一种有前途的工具是复合零诊断（CND）$ \ {s_3^1-ε\} $，其中$ S_3^1-ε$对的进化轨迹呈现不同的属性，并且可以很好地评估与$λ$ CDM的不同属性。此外，我们通过$ω_{d}-Ω^{'} _ {d} $配对分析研究了模型的动态分析。
In this paper, we have examined the Sharma-Mittal holographic dark energy model (SMHDE) in the framework of an isotropic and spatially homogeneous flat Friedmann-Robertson-Walker(FRW) Universe by considering different values of parameter $δ$ and $R$, where the infrared cut-off is taken care by the Hubble horizon. We examined the SMHDE model through the analysis of Statefinder hierarchy and the growth rate of perturbation. The evolutionary trajectories of the statefinder hierarchy $S_3^1$, $S_3^2$ $S_4^1$, $S_4^2$ versus redshift z, show satisfactory behavior throughout the Universe evaluation. One promising tool for investigating the dark energy models is the composite null diagnostic(CND) $\{ S_3^1 - ε\}$, where the evolutionary trajectories of the $S_3^1 - ε$ pair present different property and the departure from $Λ$CDM could be well evaluated. Additionally, we investigated the dynamical analysis of the model by $ω_{D}-ω^{'}_{D}$ pair analysis.
